Back when I was involved in coaching youth soccer I found the other coaches had never heard of the New England Revolution, New York Red Bulls, L.A. Galaxy, etc.
These folks were fans of man united but had no interest at all in US soccer.
Who knows? Maybe not having lockouts will mean that if some team starts playing well people will be able to watch it. MLS definitely needs something to happen to get people interested but it seems to me they should relegate the whole league.
